SHIELD FOR PROTBGTING WATER-BAGKS IN RANGES AND STOVES.

Be it known that I, M. J. WELLMAN, of the city, county, and State of NewYork, have invented certain new and useful Improvements in ProtectingWater-Backs in Cooking-Ranges and other Fire-Grates; and I do herebydescribe and ascertain my said improvement, referring tothe accompanyingdrawing, in which' the invention is shown in section.

It is well known that in winter great danger and inconvenience ureexperienced by the freezing of the pipes v leading to water-backs as nowarranged, and many casualties by explosion and bursting have arisen,endanger'- ing lives and causing the destruction of property thereby. Myimprovement is to guard against danger of this y kind, and enable thedomestic to make a fire for cooking, Svc., at all times without riskingan explosion. in the coldest weather. l

The construction is as follows:` The water-back a is made in theordinary way, with its pipes of supply and discharge, as heretoforeconstructed. The grate b and itsrelative position to the water-back'arealso of ordinary form and position. My improvement consists ininterposing between thc water-back a and the fire-chamber formed by thegrate b, a plate of metal, c, which can be brought forward into theposition shownin the drawing, so es to leave an air-space between thewater-back and the fire, through which the air can freely circulate,

and thus prevent the water-back from becoming so heated as to produce a.dangerous pressure therein. The

plate c is made to move forward and back in any convenient way by beingattached to the top plate ofthe range, as seen in the drawing, with aknob at d to move it by; or it may have an arm projecting from itbackward, and ai'lxed to the water-back, or otherwise; or it may bealxed to and form a. part of the grate, which latter will then slideforward and back with it. rWhen it is ascertained that the current ofwater is free und unimpeded through the water-baelgthe plate c can beslid back against it, and thewater heated therein as usual. In additionto the safety thus obtained, and the convenience thereof, theguard-plate protects the waterback against burning-out; and the plateitself being cheap, can readily be renewed when burnt outor injured bythe heat of the tire.

Having thus fully described my improvement in protecting water-backs inralnges, 85e., I clam.

The metallic plate between the water-back and the fire, and forming the.back of the fire-place, and protecting the water-back at all times,-soconstructed and arranged as to rest against the water-back when thewater-back is Vto be heated, and `to be moved forward and permit :tcurrent of air to pass up between the said water-back and the fire-Whenthe heat`of the lire is to be excluded therefrom, as und for the.purposes herein set forth. i.
